MOTOR TRACTOR PLOW.

Application filed November 22, 1920.

To all wiz/m 'it I77204/ concer/lt:

Be it known that we, ERNEST Bierman PELLING, a subject olf the King ofGreat Britain and lreland, residing at the Engineers House, SelsdonPark, Croydon, in the county of Surrey, England, and Vieron ALEXANDERh/nrrioir, a subject oi the King of Great Britain and Ireland, residingat 83 St. James Avenue, Beckenham, in the l0 county of Kent, England,have invented a new and usual improvement in Mot-or Tractor Flows, (forwhich we have tiled applicationin Great Britain Nov. l2, 1919, No.28,07%, accepted under No. 158,712,) of which l5 the following is a fulland complete speciiication.

rilhis invention relates to tractor plows of the self-containedanti-balancetype, and it has for its object to cause the frame carryingthe two groups or gangs oi' plow shares to tip automatically andinstantaneously on reversal of the direction of motion ot the tractor.Another object of' the invention is to prevent the idle gang of plowshares acting as a counter-balance to the gang oi plow shares at workwhich tends to lift the latter and so make the turrows of unequal depth.A further object is to enable the gang of plow shares which is beingbrought into contact with the ground after the frame of the plow hasbeen automatically tipped to be forced into contact therewith by thedriver until they have obtained a grip therein where by the servicesotasecond man can be dis- `nensed with, and a still further object is tobalance the lateral strain of the traction oic the plow whereby thesteering is materially facilitated.

le attain these ends by coupling the iframe carrying the two gangs or"plow shares to the tractor in the manner usual in anti-balance one-wayplows so that a small amount of relative movement can take place betweensaid frame and said tractor, by the employment of flexible draughttackle between each end of the frame oit the plow and the fran'ie oftthe tractor, by connecting` each end to the frame of the plow withliifting tackle which is automatically brought 5G into operation byrelative longitudinal movement between the tractor and the plow, and bythe employment oi means whereby eXtra` pressure can be exerted on theend of the iframe ot the plow carrying the gang ot shares Specificationof Letters latent.

in the accompanying drawings which illustrate this invention Fig. l is aview in side elevation ot the complete implement,

Fig. 2 is a view in plan thereof, and,

Figs. 3 and are views in side elevation showing modilications of themechanism ifor applying the increased pressure on either end oi the:trame of the plow.

Throughout the view similar parts are marked with like letters ofreference.

The type or' tractor plow to which this invention relates consists ot'two essential elements, a tractor and plow. Vllhe Afoianer comprises aframe o hereinafter called the Ctractor framewhich carries the powerunit 7;, the clutch (Z, the gear box d and the rcversing `gear c, c and(Z2, d3 and is carried by two driving' road wheels a, o and two.steering wheels a?, a2 which latter are both located on one side of thetractor trame tore and aft or' one of the driving wheels said steeringwheels being carried by forks a3 which are telescopically mounted inheads or sockets ai* carried by fore and aft extensions a* or' the framea with cushioning springs of interposed between said 'fork and said heador socket to allow each steering wheel a limited amount of independentmovement and said extensions being braced to the frame a by stay barsam. lt also comprises mechanism .for controlling the steering wheels a2,o2 which consists or' a. hand wheel c of the usual type mounted at orabout the centre ot the frame a and in couple with said steering wheelsby mechanism such as a. cross shaft c', a coupling rod e2 connecting thetwo arms a6 a carried by the forks a3, e3, a spur pinion c3 on thesha'it c and a rack c* in or on the rod e2 with which the pinion c3gears. .lt further comprises means tor reversing the position oi thedriver-s seat comprising a collar a mounted on the pillar carrying thesteering control wheel e which is free to rotate with respect to saidpillar, an upwardly projecting arm n hinged to said collar by means of ahorizontally disposed pivot and a seat n2 for the driver carried by saidarm, and two forks a3 nf" mount1 ed on the platform of the frame c foreand ai't of the collar a with which the arm a, carrying the seat engagesto bring the seat n2 into position either' tore or aft oi the pillarcarrying the steering control wheel c according to the direction inwhich the tractor is to be driven.

Midway in the length ol2 the frame f of the plow are blocks 7" each ofwhich is carried by one ot the longitudinal members of said frame. lneach of these blocks is a longitudinal slot f2 oi inverted V-shape.rllhrough these slots passes a bar g which is mounted in bearings i'reeto slide in slots h in depending brackets 7L carried by the trame c saidbar being provided with the usual screw lifting and lowering gear asshown.

Each end of the frame of the plow is coupledn'ith the brackets 7L or anyother convenient parts of the trame a', by two pairs of draught chainsm, m each pair of which is connected to the `trame j oit the plow at a Ysingle point m2 through a whipple tree fm/ the lengths of saidl couplingchains being such as will allow ot the desired amount oi' relativemovement taking place between the trame of the plow and the frame of thetractor within the limit or" the slots 742,.

Attached to each end ot the frame 7" of the plow is a chain 0 whichaiter passing over a sprocket wheel p carried by a bracket mounted onthe frame a oi the tractor at a suitable distance from the verticalplane o1 the axis ot the driving wheels a" passes round a plain pulley pmounted on one of the blocks f or on any other suitable part oi the'frame f of the plow at or about the centre o'l'its length and then runstore or att and is anchored to the frame a of the tractor at anysuitable position tore or alt of the axis ot its driving wheels so' thatit operates on the pulley block system. The effect of this coupling isthat the relative longitudinal movement which takes place between thetractor and the plow when reversing at the headlands operates to liftone end or' the frame o' the plow and consequently to lower the otherend thereof and thus bring one plow out of its plowing position and theother plow into its plowing position.

In order to increase the effective weight on the gang oit plow sha-resin contact with the ground tor the purpose ot causing the shares to getgrip oi' the land the sprocket wheels y; are each provided with meansfor rotating same for the purpose of increasing the tension oit thechain connected. to the end ot the frame of the plow which is for thetime being lifted whereby an increased pressure is exerted on the otherend oi said trame. A convenient hand operated mechanism ior rotating thesprocket wheels'consists oit' a pair of hand levers a: which are pivotedabout the axes of said wheels as shown in Figs. 1 and 2 and are providedwith means whereby they can be coupled to or uncoupled trom said wheels.Quadrante ai or other equivalent devices may be employed to retain thelevers 0J in suitable positions tor manipulation.

lnstead of employing a hand lever for operating each ot the sprocketwheels p independently a single hand lever rc maybe employed as shown in3 said lever being pivoted to the 'iframe oi the tractor and coupled bymeans ot links c to arms or levers c e pivoted co-axially with thesprocket wheels p and coupled theretoby clutches as aforesaid.

instead of using a hand operating lever a winding drum s may be employedin which case the two chains 0 run over plain pulleys p mounted inbearings carried by the frame ot the tractor and direct to said drum onwhich they are wound in opposite directions, said drum being providedwith mechanism iior rotating it by hand as shown in Fig. t. il. suitablemechanism Jfor this purpose consists ot a shaft w geared to the drumeither directly or indirectly by bevel gearing said shaft beingprovidedat its upper end with a wheel fwV for imparting motion to it.
